Advanced Searching

  • The Adjacent operator (ADJ) retrieves records with search terms next to each other in that specific order. You do not need to separate search terms manually by inserting ADJ between them because, when you separate terms with a space on the command line, Ovid automatically searches for the terms adjacent to one another. For example, the search "blood pressure" is identical to the search "blood ADJ pressure".


  • Routes of Drug Administration are the various ways in which drugs may be administered, such as "intramuscular" or "regional perfusion". If you choose "Routes of Drug Administration", you will be presented with a comprehensive list from which to select.
  • A limit to Evidence Based Medicine will retrieve results to only Evidence Based Medicine records or subsets (e.g., meta analysis, outcomes research, etc.). (Examples: Evidence Based Medicine, Consensus Development, Meta Analysis, Outcomes Research, Systematic Review)
